Poor- waited 1 1/2 hours in San Francisco for bus to turn up and no apology was given. All buses were not on time greater than the suggested wait during the 3 day period. I would recommend booking with an alternative bus company as this was not a cheap deal and not value for money.
My husband and I enjoyed the trip very much. Knowledgeable tour guides. Overall it was a great tour and I would recommend it to everyone.
Great tour as long as there is a live narrator. Audio is not as interesting as live people and the music between stops is awful
